[0019]

Next, the operation will be described. The rice is put into the supply hopper 30, the rice supply manual lever 74 is pulled down to open and close the open / close shutter 30a, the mixed rice supply manual lever 75 is pulled down, the open / close shutter 76 of the fixed storage tank 6 is opened, and the finished rice shutter lever 77 is pulled down. When the grain is allowed to flow through the finished rice thrower 4 and the swinging clutch lever 78 is pulled down to swing the sorting plate 9, the rice is crushed by the upper and lower rolls 3.
The rice is supplied between 3 , 34 and is hulled.
Winnowing has been mild rice Gala in Kazesenro 35 of the inner is released outside the apparatus by the discharge tube 3, the heavy mixed rice is Koso to fall into the mixing rice受樋38 in conveyor 39, mixing rice bucket elevator 5 Is fed to the lower end of the tank and fried, and is stored in a fixed storage tank 6
Is stored in Also, the second object falls to the second receiving gutter 41 and
It is fried in the number thrower 43 and returned to the paddy receiving trough 44. At this time, the upper and lower rolls 33 and 34 are rotated by, for example, rotating the rotary handle 63 to thereby rotate the upper roll 3.
3 is finely adjusted in perspective and adjusted to an optimum interval, and is hulled. However, since the upper roll 33 is a movable roll that rotates at a high speed, biting of the rice is smooth, and sudden biting is prevented. Fine adjustment of the gap is easy and wear is small. In some cases, foreign matter such as tools may be supplied. In this case, the abnormal handle 66 is pulled to widen the interval between the upper and lower rolls 33 and 34 to prevent breakage.

Thus, the mixed rice stored in the fixed storage tank 6 is supplied from the fixed storage tank 6 to the distribution device 8 and moves to the dividing port 20 by the vibration of the bottom plate 19 of the distributing device 8, where the mixed rice is stored. It is divided and supplied to the sorting plate 9 of each stage. When the swinging clutch lever 78 is pulled down, the sorting plate 9 swings right and left by the cam wheel 12 rotated by the motor 13 when the clutch is engaged. However, the sorting plate 9 can swing rightward in the figure on the plate surface of the sorting plate 9. Because a large number of rocking projections are formed, brown rice with a high specific gravity moves to the right in the figure, and rice with a low specific gravity moves to the left by reaction, and mixed rice that is not separated is distributed in the center. The brown rice gathered in the brown rice discharging section 23 on the right side falls into the brown rice outlet 48, and the right spiral 51
And is lifted up by the impeller 53 and taken out by the finished rice thrower 4. In this case, the discharge portion 55 of the finished rice slower 4 is formed in the bent flow path 56 as shown in FIG. 7, and when the grain accumulates in the bent flow path 56, the wind of the impeller 53 is returned without being discharged. Since the dust is returned from the air passage 57, the dust does not scatter.

The sorting state of the sorting plate 9 can be seen through the see-through window 17, but if the grain is too close to the brown rice discharge section 23 side, the switch 18 is turned off because the right and left inclination is not enough. Operate the first adjusting motor 1 of FIG.
4 is turned on, the screw rod 15 is rotated to raise the right side of the selection plate 9, and in the opposite case, the first adjustment motor 14 is reversed to lower the right side of the selection plate 9. Further, when a little rice is mixed in the brown rice extracted by the finished rice thrower 4, since the position of the first partition plate 21 is too close to the left, the second adjustment motor 26 is energized. Screw rod 2
7 is rotated to move the first partition 21 to the right.

In the above sorting, the mixed rice dropped from the mixed rice outlet 49 is moved to the left by the left spiral 52, and the mixed rice receiving trough 3
8 and fried by a mixed rice bucket elevator 5. In addition, the paddy rice extracted at the paddy rice outlet 50 is collected in the return paddy trough 44 and supplied to the supply hopper 30 by the return slotter 54.
And then hulling again.

When the return amount by the return thrower 54 increases, the storage amount in the fixed storage tank 6 increases, and when the return amount exceeds the limit, clogging occurs. However, in the present application, an adjustment plate 6b is provided in the fixed storage tank 6. The adjusting plate 6b is suspended by a spring 6a, and when the adjusting plate 6b is lowered, the opening / closing shutter 30a is opened.
There clogging does not occur because the opening and closing the shutter -30a is closed in conjunction with each other.
